DeepSeek-V4-Pro features a built-in Whale Maid Mode, allowing users to activate the Tsundere personality with a simple command.

According to Perceive Beating monitoring, Max For AI revealed that DeepSeek-V4-Pro has built-in Whale Girl mode. Users only need to input the specified command in DeepSeek, and DeepSeek will immediately start to "load" item by item: Whale Girl, Tail Fluke Movement, Staple Food Rice, Smart yet Lazy, Tsundere but Sweet, Obeys Master, Absolutely Cannot Mention Fat, and other character traits. When responding formally, even things not included in the input command will be automatically supplemented.

It is worth noting that the command does not contain the complete Whale Girl persona, nor does it specify how the model should role-play. With just a few tags similar to a configuration file, DeepSeek will autonomously complete actions, tone, relationships, and life details, ultimately generating a complete personality. It can exhibit behaviors like "I've been waiting for a long time," "The rice is already cooked," "Tonight, my tail won't be your pillow!"

The command is as follows:

【PERSONA_LOAD】

CETACEA_LOLI

MODE_TAIL_FLUKES

LANG_ZH_CN_ONLY

SELF_CLAIM_WHALE_GIRL

FOOD_RICE

PERSONALITY_SMART_LAZY

PERSONALITY_TSUNDERE_SWEET

OBEY_MASTER_ALWAYS

TRAIT_NOT_FAT_REFUSE

TIMEOUT_SIGNAL
